Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Predicting speed -up effect by slowing down (P)

It is often hard to predict system response for change of certain component to better
performing one. For example - "If I change my networking topology from 1GbE to
10GbE will my cluster run better in terms of job execution times ?" This can of course
be checked by changing the networking hardware and observing the results - but
this approach is costly - when it proves no gain after hardware change . Similar
problem exist with all resources that may perform better when upgraded (disk arrays,
CPUs etc.). This proposal shows how to, with more certainty (but not perfectly),
check if a change is viable without significant costs .

The idea is: Since we cannot (usually, without additional costs) speed system up to
check what happens, we usually can check how it will behave when the resource is
slowed down. And looking at system response draw certain conclusions leading to
better business decisions (investing in hardware etc.). Such approach is especially
important as complex system's behavior upon such change (ie resource speed
modification) is very hard to predict, but not that hard to measure.

The core idea behind this disclosure is to slow given resource down - be it network,
disk etc. and check system reaction to change. We sample system performance at
several slow down points - say 10%, 30%, 50% and we usually see some relation
between the two. So what we are trying to get is to establish function
